Turbotax says my Employer HSA contribution on w2 is wrong

My employer contributed $600 to my HSA and I contributed the rest of $3050. box 12 code W on my w2 is $3650, but Turbox says "We found something wrong" and ask if some of my HSA went to my spouse. (No, it didn't) but I don't understand why turbotax says it's wrong since the limit is $3650.
