I am trying to amend my Mom's return with TurboTax online regarding the incorrect calculation of the taxable portion of social security benefits. I tried what you suggested, but I'm not having any luck doing this in TurboTax -- it is still pulling in the incorrect taxable portion based on using the SS Benefits Worksheet from the IRS. Am I going to have to file an amendment manually vs. using TurboTax? THANK YOU!
