There appears to be an error in how estimated tax payments are placed into columns A-D on line 10, and there does not appear to be any way for me to correct the error. A payment I made on June 8 should be in Column B (payments by June 15 for 2Q) but it is reported by TurboTax in Column C (payments by Sept. 15). This error in the assignment of my estimated tax payment on June 8 to Column C, leads to a calculation that I underpaid in 2Q, although no underpayment penalty is calculated.
