Hello: I think the SS taxable portion is still being calculated incorrectly by TurboTax. The IRS Instructions for 2023 Form 1040/1040-SR provides a worksheet to calculate the taxable portion of Social Security payments (pg. 32 of 114 pages). The worksheet contains 18 lines that are used to come up with the proper amount to be shown on 1040 line 6b. In my case, allowing TurboTax to calculate the amount, it plugs in $3,869. Running the same numbers through the IRS worksheet, it shows it to be $6,196 (big difference). I think the program is looking for a simple solution when it is a multi-step ITTT calculation. I think I'm going to need to file a 1040-X to fix this problem. It also throws off my state return. I look forward to hearing if my observation is correct.
