EV Tax Credit

In 2024, I purchased a used EV that qualifies for a $4000 EV tax credit. When I submitted my tax return on Turbotax it was rejected by the IRS because there was a problem with the EV tax credit. I found out that the dealer never submitted the vehicle information to the IRS ECO portal. I've been hounding the car dealer to get them to enter the vehicle information since the IRS made changes to allow dealers to enter time of sale information now for sales in 2024. The dealer has been very unresponsive, so I had to submit my return without the EV tax credit and hope to amend my return in the future if I can get the dealer to do their job. 

 

How long do I have to amend my return? Do you have any advise for dealing with this issue?
