TTax Desktop says I have to enter EXACTLY what a 1099-R says, then disallows what it says!

Desktop TurboTax, Windows 11

When I get to the 1099-R for an annuity we have, it says 

"Type in the amounts in boxes 1-17 exactly as they appear on *****'s 1099-R."

OK, straightforward enough.  So on the form, box 9a says, "Your percentage of total distribution" and the amount is (exactly) 0%.  So I enter 0.                                                                                                         

But when I go on to the next box, TTax clears the 0 and pops up a message saying, "The value entered must be equal to or greater than 0.01"

So what can I do???   I entered exactly what is on the1099-R, and it won't allow my entry. 

Anyone else see this?  What can I do?  I suppose I could just skip that box, but what would be the result of leaving it blank?
