Can I still claim my stimulus check after filing taxes ?

Yes if you are asking about the third stimulus check that is just coming out. That $1,400 payment is not part of the 2020 income tax return. It is being sent separately.

If did not get one or more of the first two stimulus checks from last year—or received less than you were entitled to—those amounts were added to your tax refund. But you had to compete the Recovery Rebate Credit screen on TurboTax.

The IRS has said it will fix incorrect stimulus amounts, but it will not compute the stimulus for you.

You will have to file an amended tax return if you did not do the stimulus section. You can amend your return in TurboTax starting March 25.
