You are too late to use online TurboTax for a 2021 tax return. The only way to use TurboTax now for 2021 is to purchase the CD/download and use it on a full PC or Mac. You cannot use it on a mobile device of any sort. And the return cannot be e-filed; it can only be filed by mail now. You have to print it, sign it in ink and mail it in.
Or you might still be able to use the software on the IRS Free File site.
Use this IRS site for other ways to file for free. There are 8 free software versions available from the IRS Free File site

Don’t forget your state. And you will have to print and mail your returns. So be sure to attach copies of your W2s and any 1099s that have withholding on them. You have to mail federal and state in separate envelopes because they go to different places. Get a tracking number from the post office when you mail them for proof of filing.
