HSA over contribution AND not eligible - different years, different issues

Best way to handle this?  Just noticed this today (Jan 16th, 2020) multiple errors in my HSA account. 

 

Background: Was on a HDHP plan in 2018 and 2019. 2020 NOT on a HDHP plan so not eligible.  Have employer and employee contributions directly deposited through paycheck. Did not realize employer contributions factored into limit.

 

2018: Over contributed by $180. Had my taxes done by accountant and did not notice over contribution when she filed. Did pay the 6% penalty ($11) so really didn't cause alarm.

2019: Over contributed by $1800.

2020: NOT eligible but employer still contributed $150 on January 2, 2020 and directly deposited my employee contribution of $264 on January 10th.

 

Called HSA fund. They refunded my employer the $150 they contributed (Still need to verify they receive it but may take a minute as it's federal govt).  

 

So questions:

1.  Do I fill out the excess contribution form for 2018 + 2019 + 2020 "excess" contributions even though technically 2020 I was not eligible?  The HSA fund (BlueFund) is looking into how to calculate any "earnings" I made with it but has yet to get back to me.

2. Will I get a 1099-SA for 2019 if I withdraw it now before tax filing?

3. How do I handle the 2020 issue? I think my W2 will show i contributed $264 but hopefully I would have withdrawn it this month. I am also hoping my W2 does not show employer $150 contribution since technically it's been returned. 

4. How do I go about addressing all of this in turbotax for 2019 and 2020?

 

My head hurts.  Greatly appreciate any advice with this.
