I am on a telephone hold. However, I believe there is an issue with Turbo Tax Deluxe Desktop for MAC. I believe it occurs on Line D of the Smart Worksheet (1040 Line 6) labeled "Earlier Year Tax Return Smart Worksheet for Social Security Lump Sun Benefits. I received a lump-sum benefit in 2025 for the 2024 tax year. The calculation use my taxable social security benefits from 2024. The system automatically and incorrectly input a taxable amount $21,762 from my 2024 return. However, my 2024 return actually shows a TAXABLE amount of of $25,602 (85% of gross benefit of $30,120). 85% of $25,602 is $21,762. Thus, the 85% was calculated twice in error. I cannot manually change this amount. Please let me know how to proceed as soon as possible.
