My wife received an SSA-1099 that includes a lump sum paid in 2018 for 2017. This sum (and more) was paid by LTD in 2017 and reported on our 2017 tax return as income. We paid this sum back to the LTD carrier. Turbotax deluxe lets us show the sum was for a previous year, but there does not appear to be a way to show taxes were already paid on this sum last year as income (not taxable SS payments). How do we avoid being taxed twice? The carrier pointed me to IRS-pub 915, but I how do I do this in Turbotax?
