I sent two checks to the IRS for estimated income tax last year. Using form 1041 (it's a trust) I am directed to Tax Payments Worksheet. Part 1 is titled 2024 Estimated Tax Payments. I'm to enter the Due Date, Actual Date, Amount Paid, Payment Method, and Bank Account Number. (There's a fourth option for those who use EFTPS.)
My bank account number is 8 digits, but the software only permits me to enter 4 digits. My guess is that I should enter the LAST 4 digits. Is this correct?
(I called the IRS and got through rather quickly. The IRS representative told me to call TurboTax!)
