Sorry you can't install Turbo Tax on a iPad or mobile device. Only on a full windows or Mac computer. Either get a refund or find a computer you can install it on.
If you install the program you will need to download the .tax2021 file from the Online version. It may not be available for awhile as they switch over to 2022. How to fix or finish a prior year return you started online
