Parent passed early 2020. Estate closed. Do I have to file the final 2020 return.

Now have what I believe is all of 1099's.  They total approximately $16,600 broken down by :

1099-R state pension of $1,400.

1099-SSA $1,200.

1099-INT/DIV $3,000.

1099-LTC refund $11,000.

That are the ONLY 1099'1 received so far.

 

Do I have to reopen the estate and file a final 2020 return?  If yes, can I file it with Turbo Tax 2020? 

 

Thanks in advance.
