each PTP stands on its own for tax purposes. losses (lines 1 through 3 and others as well ) are passive and can only be deducted in future years when there is passive income from the same PTP to offset the losses or you fully dispose of the PTP in a taxable transaction.
what you can do is extend the return and include as many of the PTPs as you get but file by 10/15 to avoid the 4.5% monthly (max 5 months) late filing penalty. then amend to include all the omitted k-1s. if you owe additional taxes, you are only subject to the late payment penalty of .5% a month.
This still leaves the issue of omitted k-1s that you fully disposed of during the year. disposition may result in depreciation recapture to the extent depreciation was included in the income/losses reported in the current and all prior years you owned it. Currently, this is reported on line 20AB of the k-1 and also on the supplemental sales schedule that you should get as part of the k-1 package. Not all k-1s have this recapture - companies that conduct business activities. in some cases, the recapture can exceed the suspended losses.
