Entering the total amount you put into a traditional ira for 2023

I put in $600 of my taxed money into a Traditional IRA for 2023. When I put the amount into block, it says I owe money but it was taxed already. Whart am I doing wrong? No, I have only contributed $600 total this year. I have no Roth. It’s a 401k Traditional IRA. I did not come close to the $6500 on contributions. I have already entered my 1099-DIV under Interest and Dividends.
