2016 1040 Income was only 1,060, HOH, std deduction 9300, 1 Dependent. Do I enter $0.00 or the negative amount on the line 41?

2016?  You cannot file a 2016 tax return using the TurboTax online editions.  The online editions are only for tax year 2020.

TurboTax does not support tax year 2016. 

Any 2016 tax refund has been forfeited since it is now beyond the 3 year statute of limitations for receiving a tax refund.

I am aware I cannot file online.  My family has been using TT for several years.  And I thought this would be a good place to ask.

Thank you.

Thank you for replying.  I didn't know if I needed to still file even though it is several years old.
