Deductions & credits

The reason I wanted to file by tomorrow is because I accidentally missed by 3 days the Jan 15 deadline to pay 4th quarter estimated taxes. Because I've never paid estimated taxes, I didn't think about that in time, and I just converted a Traditional IRA to a ROTH in the 4th quarter. My percentage of taxes in 2022 on our joint return was zero because I wasn't working. So, it may be that I don't have a penalty anyway. I'm unclear on that. But, I was trying to avoid the penalty altogether, if there is one, by filing by Jan 31st. I have no idea how to calculate the penalty to know if it is worth waiting for the employer to correct this issue with the wrong form.
