Avoid penalty by paying 2019 estimated taxes late but before July 15th 2020?

Hi,

I was unable to pay most of my estimated tax in 2019 (only made one payment). TT now shows that I have a penalty because I didn't pay enough estimated tax. I'm wondering if I could just send the IRS one check that covers the entire estimated taxes I still owe from 2019 before the new federal tax day, July 15th. Or will I get fined either way because the payments are not spread out quarterly and on time? Hoping to avoid the penalty if at all possible.

 

Any help is appreciated, thanks!
