Get your taxes done using TurboTax

I made Fed & State extensions for TY 2020 by May 15, 2021.  Massachusetts extension good to Oct 2021 (for 2020 return). I suppose I will be late since it is now Nov. 21, 2021 -- and for the portion since Oct. 15, 2021?  Is that correct?  [I have also paid most of estimates for 2020]

 

2nd question:  In the Mass. State return (and Federal return) I don't see where to enter that I did file extensions for Fed and State.  How does TurboTax 2020 know then what dates to compute any possible penalty or interest? (should be Oct., not May. Correct?)

(I think I saw that the State is charging a larger sum than I would have expected. )

Thank you!
