Get your taxes done using TurboTax

I totally understand my taxes - which are due May 17th and that is totally different than the estimated quarterly tax.  Until I did my taxes on TT a few days ago, I didn't realize I needed estimated quarterly taxes paid.  I am recently retired.  

 

My only question is, I paid the estimated quarter tax due April 15 on April 17th.  Will I get penalized?
