I rec'd a $4200 distribution from an inherited ROTH

My cousin's passing left me with both a traditional IRA and a ROTH. I received a $4200 gross distribution from the ROTH, taxable amount not determined is checked, distribution code is T.

 

TT says this is a nontaxable distribution. I'd like confirmation that this is correct, please. I know the Traditional IRA distribution IS taxable.

 

Thank you.
