if I claim my daughter that is in her twenty's as a dependent that does live with me will I get her full stimulus checks with my refund and the only reason I'm doing my 2020 taxes is for my stimulus nothing more not doing state taxes or nothing and im Qualified for 1800$
A dependent over age 16 is not eligible for the stimulus. Also if you CAN claim a dependent, reguardless of age, the dependent cannot claim them self.
For 2020, there is no stimulus money for dependents over 16. The first two dependent stimulus payments ($500 and $600) were only for children under 17.
The third stimulus ($1400) is for all dependents, regardless of age, but is technically for tax year 2021. If you file a 2020 return, claiming your daughter, there's a chance the IRS will send you a $1400 deposit (separate from your own 2020 stimulus/refund). Otherwise, you will have to claim it when you file your 2021 tax return AND she must still be a dependent in 2021. If she is not your dependent, in 2021, she will will be able to claim the $1400 by filing her own 2021 tax return (in early 2022).
