Ok ... well until the return is ready to file you don't have to pay ... the price will not go up until early March so there is no rush. This is normally done in step 1 of the FILE tab.
Option B :
To view your entire return using the online editions (including the state) before you file, you will need to pay for your online account.
To pay the TurboTax online account fees by credit card, without completing the 2020 return at this time, click on Tax Tools >>> Tools and then Print Center. Then click on Print, save or preview this year's return. On the next page, to pay by credit card, click Continue. On the next screen it will ask if you want Audit Defense, if you do not want this option just click on the Continue button. The next screen will ask for all your credit card information so you can pay for the account.
