Get your taxes done using TurboTax

I have the same situation, with information in both blocks 1 and 2 on my K-1 and TurboTax says I have to split it into two K-1 Entries.  However, it says I should have received a form that would tell me how to split it, and I didn't.  Are there any blocks which I should not simply prorate based upon the amounts in blocks 1 and 2?  For IRS purposes will the two entries be put back together?  Does it really make any difference what I put on the two K-1s so long as the total is correct when they are recombined?
