PTO does not really do much for 1291TAX.  In fact, F.8621 in PTO is almost a dumb form.  You have to run all the computations offline and plug in the numbers.  The "smartest" things it does are to flow the 1291TAX you entered to F.1040 Line 12a and the 1291INT you input to Sch 2.  You still have to manually input the rest everywhere else.

If you have numbers on F.1116 for 1291, you must have entered some numbers somewhere.  You may want to double-check your entries.

If you could offer more info, someone may be able to take another stab at it.
