I received a lump sum SS payment for 2019 in 2020. The Home and Business TurboTax does not seem to be calculating correctly. The 2020 1040 SR 6a SS benefits is my Box 5 amount on the 2020 SSA 1099. Box 6b amount is the Box 5 amount less the 2019 paid amount of $13,144 at the bottom of the 2020 SSA 1099 plus 297.00 ADDED to the 2019 amount shown on the 2020 SSA 1099. A summary page for 1040 show the amount of $13441 as Social Security non-taxable. The Lump sum worksheet for FORM 1040 LINE 6 shows Taxable benefits under lump elections as 45,349 compared to the actual 6b amount of 39,911.
