I bought a new car in 2022. I want to enter the sales tax but the "Easy Guide" isn't giving me the option. How do I enter it?

The first time I entered the Sales Tax section it asked me if I had made any major purchases.  I didn't have the paperwork from the dealership at the time, so I backed out of that section.  Now I can't get back to the screen where it asks for the sales tax on major purchases.
