No, I'm not using TurboTax to do returns for clients. I was just searching the web for answers to this situation and this site popped up in the results. I used TurboTax for my daughter's return this year, as I have in previous years.
The 2015 W-2 only includes the 2015 health costs, but later, in March 2016 some of those 2015 costs were refunded to the company. This will cause the 2016 number to go negative. I'd rather not do an amended 2015 W-2 if I don't have to. Should I just do an adjustment for 2016 to show it as zero in this box? Otherwise it will be negative.
