Last year I had used TurboTax desktop version, and this year I was planning to use TT Online.
But after this complication arose whether I have to manually add 1116 carryover statement, I thought to avoid problem, best to purchase TT desktop version.
Once I did that at start up it then read the old 2019 tax file. So though I did not have any Tax Credits to claim this year, I see it auto created a blank Form 1116 and also attached the CarryOver Statement for future tracking to the Federal Forms that are required for Filing.
So to the others who may have the same as my question - YES you need to attach it, even if not claiming credits for the year, so carryover are not hidden in the years they are not claimed.
