After the March 1st TT update, I filed my return and it was accepted. But NO changes had been made to my return! So perhaps the IRS made a change in conjunction with the TT update... But while I was waiting to see if it was accepted (I had little hope!), I tried another workaround I read about somewhere in this thread. Under PERSONAL>OTHER TAX SITUATIONS>ADDITIONAL TAX PAYMENTS>UNDERPAYMENT, the 2017 liability should have been zero. When I changed that field, it miraculously eliminated the 2210 entirely!!
