Get your taxes done using TurboTax

you need to create 3  k-1's one for each of the PTPs shown on the supplemental schedule use their EIN then enter the amounts shown for each on the respective k-1.  this is necessary since each PTP stands on its own and the profit reported for SUN (lines 1 and 2) can not be offset by the loss from the other 2

you can ignore the k-3

you can also ignore the following lines  - Turbotax doesn't use them and they have no effect on your taxes.

line 18c, line 19A,  and all the info on line 20 except for line 20Z which is entered separately on each of the k-1s

this is the199A which is -192 for ET

199A -19 for USAC

199A  32 for SUN

in addition since the 1231 is a loss that's 199A also.
