SEP mistake

I had a synchrony bank account misrepresented by them as a SEP.  It was only a CD and I only just found out this past week when I went to do a RMD.

They told me that this was only a CD and not a SEP and it took me over 2 weeks to find this out.  I deposited in March of 2024 for my 2023 taxes.  I reported these as SEP on my IRS income taxes in Turbo Tax.

 

How do I correct this with the IRS now in 2025?
