I'm not quite sure from your description what the problem is exactly but I will have a stab at offering some help...
I am assuming you are using Windows (I am unfamiliar with the Mac version and whether the controls are the same so your mileage may vary).
At the very least, to begin playing with formulas and fractals, you need to see the Layer Properties window. If this is not visible on the right hand side then press Shift+F2 or use the Window > Tool windows menu to summon it into view. You can have it floating around if you wish or docked on the right.
I will just add that if, for some reason, you cannot see all the details that you think you should be seeing just hover your mouse over the horizontal line at the bottom of the tool window... it may be that parts are hidden... try clicking/dragging that line up or down to show more or less of the work area on that window. You can adjust the height of all those long thin windows to suit your needs. It's many years since I looked at those tutorials but I think you should still see pretty much what is being described. The design and colouring of the windows may have been updated but basically the underlying functions and layout are very similar, if not the same as that of a few years ago.
Back to your question about modifying the formula... the middle tab of this Layer Properties tool window is labelled "Formula". Click on this tab to see the parameter area where you can play with the numbers to change the structure of the formula (in conjunction with zooming and generally using your mouse to further explore the formula in the fractal image window using click& drag and other actions). Changing the Starting Point (often also called Seed or Start value or similar) on the Formula tab can yield interesting results straight away - try right-clicking in these input slots and choose "Explore" to get a live preview of the changes when you move the mouse around in the Explore window that pops up. Click when you find something pleasing/interesting.
To change to a different formula click on the top right (yellow-ish) icon on this tab - a browser window will open where you can explore the hundreds of formulas available to you. If you have an idea of what you want you can search for a formula here. You will, of course, have had to have downloaded all the formulas before you can do this - look up the Help about how to Update Public Formulas if you haven't done so already.
Also on this Layer Properties window, is a tab on the right labelled "Outside". This is where you work with an "Outside colouring" (some formulas use an "Inside colouring", there's a tab for that one too). These Outside/Inside colourings are another type of formula that add different shapes, details and/or texturing to the skeleton of your formula design. You can add colour here too.
I hope that this very brief introduction helps you get started! I would suggest you try and persevere with the Help tutorials as they will give you some basic instruction on how to do things in UF. The formulas and colourings suggested have been selected because they are good ones for beginners. Good luck!
