Same thing for me. How did you get this issue resolved:?
I had estimated payments in 2018 and used TurboTax Premier and it did NOT automatically create a Schedule 5, instead it incorrectly lumped the payments into Line 16 of the 1040, which is wrong b/c that line is for amounts shown on W-2 or 1099. I couldn't get the system to generate a Schedule 5 so I think it's a glitch. For what it's worth I used same software last year and manually entered these amounts and they showed up on Line 65 of my 1040 - correctly - so the amount should have shown on a Schedule 5 this year.
