Get your taxes done using TurboTax

The publicly-traded partnerships that indicate a K-3 is included will not have them available until July. I am not a big investor, not even five figures. I don't want to extend my tax return and delay any refund, so I am inclined to indicate no that the partnership does not have a K-3. Therefore I have two questions below.

1. If stock investment activity notes some foreign income and foreign taxes, do I need to include K-3s and enter K-3 data and therefore extend my return?

2. What are the consequences for unchecking the box that there is a K-3 and not reporting any data for it when other stock activity includes foreign income and foreign taxes?
