I have a second w2 to file but the app closed while filing, when I reopened it, the second w2 was never uploaded and I haven't put the info in. Site is trying to wrap up without my second w2 info.

Once a tax return has been filed it cannot be changed, canceled or retrieved

You will have to wait for the IRS to start accepting or rejecting 2020 tax returns on February 12, 2021
If the return is rejected you can make the necessary changes and e-file again.
If the return is accepted you will have to amend your original tax return. An amended return, Form 1040X, can only be printed and mailed to the IRS, it cannot be e-filed. The IRS will take up to 16 weeks or longer to process an amended tax return.

Before starting to amend the tax return, wait for the tax refund to be received or the taxes due to be paid and processed by the IRS.
