Form 8936 Error

I filed mid February but my return was rejected due to an error in Form 8936.  The tentative credit amount in Box 4c was correct but the number in Box 4a was incorrect.  I had to wait until February 20th for TurboTax to fix it.  I returned to TurboTax and clicked "fix the error" then took me to the e-file section.  After submitting, I checked the print out and noticed that it's still wrong.

 

I have a Tesla purchased in April 2019.  Box 4a should be $7,500, Box 4b should be 50% and Box 4c should be $3,750.

 

TurboTax have Box 4a$3,750, Box 4b50% and Box 4c$1,875.

 

So I have lost $1,875 in credit.  If the IRS don't reject my return again then TuboTax suggested that I have to wait until next month to file an amendment.  In the meantime, the IRS are going to take $1,875 too much and I'll have to wait a long time to get it back.  I know this because TurboTax also had and error in last years return.  Their other option was for me to pay another $200 to talk with a Live CPA to see if they could offer a better solution.

 

This is the last year I'll be using TurboTax.
