Box 12w on my W2 shows $5500. When i go through the steps in turbo tax, i have not entered in any additional values for HSA anywhere. Why is it saying i overinvested?

according to the IRS, $7100 is the limit for a family and my HSA investment, through my employer, has not exceeded this amount for my family of 4.  Not sure why the turbotax tool is triggering this over investment.
