there is a lot of paperwork with any PTP especially now that the IRS has expanded foreign reporting to encompass a 20-page k-3. the amounts you receive are not dividends and are not taxable unless they reduce your tax basis (for you to compute because Turbotax doesn't) to a negative amount. if you think entering the k-1/k-3 data is mind-boggling wait until you dispose of it.
by the way, there should be a supplemental schedule because ET is really 3 Partnerships and under the tax laws each is supposed to be reported separately - probably a lot of taxpayers ignore this. so the one k-1 you got is supposed to end up as 3 k-1s in your return.
the k-3 you can ignore unless you are not a US citizen or own more than 10% of ET.
EBIE is excess business interest expense.
note if 13K is zero you do not file form 8990. leave the line blank
line 13 Code K. Excess business interest expense. If the partnership reports excess business interest expense to the partner, the partner is required to file Form 8990. See the Instructions for Form 8990 for additional information.
Turbotax, as you know, does not do form 8990.
EBIE has nothing to do with whether you take the standard deduction or itemize. so yes you are supposed to file 8990 which would also require filing by mail since there is no way to attach a manually prepare form to the e-file
