If you have not completed the section that asks about your spouse's eligibility for HSA contributions, make sure that's completed correctly. Also check Form 8889 to insure it properly reflects the $4500 allowed limit and shows the $4500 employer contribution (you may have inadvertently doubled it).
I noticed that TT has not updated the HSA limits to 2019 amounts so that's also an issue with yielding the correct result as far as limits.
