Can I take dependent off my 2020 tax return, that has already been filed and accepted?

Come back at the end of the month, when the 1040-X form is ready here. But if your goal is to do this so that the Dependent can get his/her own stimulus check, it doesn't work that way.  If the person is eligible to be your dependent, they cannot "claim themselves," even of you choose not to.

david is 27 has never worked a job, we've never got Social Security for him. The only thing to his name is a Social Security number, birth certificate, and a drivers permit. He also has never filed anything in any system.
