Deductions & credits

I too have a similar issue. I have a dollar amount in 12b. W is used, and the dollar amount is $499.92. My employer did not contribute anything to me. I contributed. I was told it was an FSA, not an MSA, because I was not able to have an MSA, because I do not have insurance through my work. I am covered under my husband's insurance. I thought there might be an issue with the way it was noted on my W-2, but our payroll person said they put all cafeteria type plans under 'W'. I do not have an HDHP plan. What should I do? TurboTax is not allowing me to bypass this issue.
