Wrong Electric Vehicle Credit

I filled out my 2019 taxes with an Electric Vehicle credit but it was calculated wrong by TurboTax.  I submitted the return.  Now TurboTax has been updated and it is asking me to submit an amended tax return.  That is fine but the initial refund was over $6000, now it shows that I owe over $3000.  

The calculations are technically correct but it is assuming I received the money already from the IRS.  Do I send the amount I "owe" even though the wash of the two returns will be a $2500 refund to mer?  What is my liability to send in the extra owed money if I never received the first too large refund?  Will the IRS send me the original $6000 refund?

Help?
