is there a cover letter? it might tell you if there was foreign-sourced income. if none and you are a US citizen they'll be nothing to report when you get the k-3. so if this is your situation i would suggest unchecking the k-3 box - a must if you want to e-file. you could always amend it later if needed. it's unlikely your taxes would be higher. if there is an amount on line 21, that is from foreign-sourced income so the k-3 will be needed. to e-file before you get the k-3 you would have to leave off the FTC and uncheck the k-3 box. yo could amend later to claim the FTC. it's your decision.
