No one at TT knows if the IRS is sending you the 2021 stimulus $. The IRS has identified some people who filed 2021 returns and appear to be eligible but who did not use the recovery rebate credit on line 30 of their 2021 return. The IRS is sending out that money during January to those folks. We do not know who they are and cannot find out. If anyone could claim you as a dependent, for 2021, you will not be eligible.
Look at your online account with the IRS to see if they send you $1400 in 2021.
