Please keep your related questions in one thread. TT would not have put that Recovery Rebate Credit on there unless you incorrectly answered NO to the stimulus #2 question. Did you actually get that stimulus after you filed your tax return? Or maybe you were thinking about stimulus #3, which had been announced, but not yet distributed? [Disclaimer: I am a user volunteer, not a TT employee.]
Going forward, you can change your withholding so that you do not have to wait for a refund at tax time next year.
