OK. Thanks for the helpful links. Now I understand what AGI is. I have no problem to send e-file. I sent e-file last year too. But IRS later send the file back to quest a signature on a missing part ( I guess it was on the last part). This year I followed all steps and are ready to make TurboTax payment, but still didn't find anywhere to ask me enter AGI or PIN. I'm afraid I will receive a letter from IRS again this year. Will the e-signature show on the proper place automatically?
