After you file

I found the reason! Line 30, how does this get populated? It shows $251 and the IRS subtracted this amount from the Turbotax-calculated refund amount and therefore, $1027 - $251 = $776. Is line 30 populated by turbotax or by me? I have never heard of a Recovery Rebate Credit so I am thinking turbotax put that amount in there by mistake. Can someone follow up to let me know how this occurred? Thank you!
