Informational Returns filed under the return employer ID number, Y/N to file electronically

TurboTax Business:  Just before completing to file electronically, there's a Y/N question.

Informational returns (W-2, 1099, K-1's, etc.) filed under the return employer ID number. Y/N

I don't understand the exact meaning.  Our husband/wife LLC always files 1065 and of course 2 K-1s are generated and efiled together.  We use the K-1 to complete our 1040 a month later.  Never gave any of that a second thought.

This question has subtle unknowns.  We never "filed K-1s" in the strict sense of sending them to the IRS prior to filing the 1065.  Info at IRS.gov says K-1s should be "issued" to husband/wife teams, almost deliberately excluding "filed."  We have no employer, wear K-1s ever "filed under the return employer ID number" if there is no employer?

I don't think the answer itself is the least bit important until it's simply used to match up our filing history for some identification process to confirm Efiling.  I don't want to say we did if we didn't, and I don't want to say we didn't if we did.

Another TT customer asked this question very carefully with a lot of supporting documents, but the help avoided the entire question and said, LLC file 1065 so K-1s required and the answer is yes.  Worthless answer.
