Need help on estimated taxes

Hi, I filed my 2021 taxes back in February like I do every year with no issues. I have never needed estimated taxes before.

 

Back at the end of April I was laid off from my job and given a 7-month severance payment.  So, for the first 5 months and my 7-month severance I had taxes taken out on W2s.

 

I took a 1099 contract job for July and August.  September, I started a new regular W2 job.  My wife and I file jointly, and she works most of the year on a W2.

 

Do I need to file estimated taxes for my untaxed wages for July and August?  Also, how the heck do you do it if I already filed my 2021 taxes with Turbotax?  I can't quite figure it all out.  Help.  Thank you.
