Sunoco K-1 Supplemental Information (Box 20)

A client received a K-1 from Sunoco that includes an additional sheet of supplemental information with codes and amounts for Box 20. I haven't seen one of these in a few years, but I thought there was a separate worksheet for entering this information (e.g. Section 751 gains, Gross Receipts for Section 448, etc.).

Can someone point me to it, or a form/worksheet where this data is to be entered?

Thanks!

Is any of that information relevant to the tax return you are preparing?

The more I know the more I don’t know.

Possibly.

Section 199A - Yes.

Section 448 (limits on cash method) - Probably not.

Section 751 (unrealized receivables) - Probably not.

Bonus depreciation adjustment for non-conforming states - Yes.

For the 199A just use 20% of business income unless your client is in the income phase out or if client is a SSTB.

section 448, 751 just ignore.

depreciation will be on state return, and may or may not apply depending on state use entities K1 instructions.

also how much money are we talking about on the k-1 - a lot of these have very small dollar amounts

Some are small amounts that are unlikely to impact the balance due or refund due. Others are in the hundreds of dollars.

199A is commonly called Qualified Business Income. Isn't there an input field for that?
