I finished filing and my unemployment I got for two weeks never came up and I just realized this. What do I do now?

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 return 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.

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.
