OK I know it is a horrid form but it is indeed mandatory; Just bear in mind that the instructions to the 8865 say (at page 10) that this form should take you the following amounts of time to deal with:
Form 8865:
Recordkeeping - 89 hr., 21 min.
Learning about the law or the form - 23 hr., 16 min.
Preparing, copying, assembling and sending the form to the IRS - 36 hr., 26 min.
Schedule K-1 (Form 8865)
Recordkeeping - 10 hr., 31 min.
Learning about the law or the form - 35 min.
Preparing, copying, assembling and sending the form to the IRS - 48 min.
Schedule O (Form 8865)
Recordkeeping - 12 hr., 12 min.
Learning about the law or the form - 2 hr., 22 min.
Preparing, copying, assembling and sending the form to the IRS - 2 hr., 41 min..
Schedule P (Form 8865)
Recordkeeping - 5 hr., 15 min..
Learning about the law or the form - 35 min.
Preparing, copying, assembling and sending the form to the IRS - 42 min.
To summarise, you cannot rush this form as it is highly complex and is designed to be time consuming. The crucial aim of the 'project' is to get the K-1 correct so that the correct figures carry to Schedule E, form 2555 and form 1116.
