if you entered your 2020 w-2 it is most likely your return will be rejected. this won't occur until after e-filing opens on or about 1/24. until then do nothing. do not change your info until after you get the rejection notice. read it carefully because there can be multiple reasons for rejection. then you can fix your return and re-e-file.
you are not filing an amended return because the original was never accepted.
