Get your taxes done using TurboTax

all of the following assumes you are a US citizen

you mention ET 

the K-3 has the following sections checked 1,2,3,4,9,10

PART: 

1) other forms but they are not specified

2) all US income so there's nothing to report for form 1116

3) this is for apportionment and allocation of research and experimentation expenses for foreign tax limitation purposes but ET reports no FTC so this section is irrelevant

4) for preparation of form 8993 to determine section 250 deduction. but this only applies to domestic corporations and US individual shareholders of controlled foreign corporations making a section 962 election. IRC 962 election is an election to be taxed as a Corporation. And, most taxpayers would not want to elect to be treated as a corporation and then become double taxed.

9 and 10 ) appear to be for foreign partners.

 

so to sum it up it would seem the k-3 for ET is totally irrelvant for your US taxes. (by the way, Turbotax can't handle most of this info only section 2 when needed). if other sections apply to a taxpayer they would have to enter the numbers directly on whatever form or schedule they apply to and many of these forms are not covered in any version of Turbotax..

 

 

now for EPD 

all that supplemental info on the k-1is irrelevant except for

20Z1 - you should get to a question about 199A income/ QBI asyou go through entering the k-1 info. 

20AH state depreciation adjustment - if needed you can get a state k-1 From EPD

 

now for K-3

same as for ET with the following differences

Part

1) form 5471 is checked

5471 is for those US individuals who hold a 10% or more stake in a foreign corporation or who are an officer or director of a foreign corporation.

the 5471 info would come from K-2  - you didn't get one, and K-3, part 5 which is not applicable for EPD

😎 (59(a) not handled by Turbotax. this information is relevant for partners completing Form 8991. This Part VIII of Schedules K-2 and K-3 must be completed for corporate partners who are determining if they are subject to the Base Erosion and Anti-Abuse Tax (BEAT), 

so here to there's really nothing to enter for the K-3
