If you have a workplace plan, it is reported on your W-2 only. Later in the HSA interview, only enter additional out of pocket contributions that you made directly to the HSA bank not through payroll. If you enter workplace contributions here, they will be double counted and you may get an over limit error; you would also be getting a deduction that is not allowed. The HSA contributions via payroll were already removed from your box 1 taxable wages, you can't deduct them again.
Although I can't see your return, one way to get a $250 "excess" calculated from a $4500 contribution is if you are over age 55, covered by a family HDHP, and entered the contribution twice. That would be $9000 minus the over-50 limit of $8750 equals a $250 excess.
