I was on self-covered plan entire year. Spouse was on a self-covered plan in January and then family plan through employer February-December to include spouse+child. Spouse had $6506 employer contribution and $594 self contribution. I contributed $2423 according to Box 12 of my W-2 (but $135 was made for the 2019 tax year).
If the code-W amount got incorrectly allocated between you and your spouse, you might need to delete both Forms W-2 and both Forms 8889 and then reenter them if there was a mistaken allocation of the code-W amounts. But perhaps that's not really the problem.
When going through the HSA section for your own HSA, make sure that you indicate that your employer told you about other contributions and that you indicate that $135 was for 2019.
You have a $2,288 excess contribution between the two of you ($2,423 minus $135). The maximum is $7,100 combined. With your spouse having contributed $7,100, any amount that you contribute to your HSA creates an excess contribution. You can allocate that $2,288 excess between the two of you any way that you wish, but it's generally easiest to allocate it all to one of you so that only one return of excess contribution needs to be done.
