If the K1 I received shows a loss, do I need to enter it in this years tax return or wait until I sell the units or get positive activity in a future year?

The K1 shows the loss reducing my cost basis.  Per the K1 instructions if the net result is positive the info should be reported on your 1040:  if negative the loss will be suspended until there are positive returns or you sell the units.  So it's confusing whether I should enter it this year in turbo tax.
