The K-1 is referring to a statement that explains the dollar amounts you have available to uses, that should have come with your K-1 to show you what would not fit on the form. You must get the information from the preparer of your partnership return.
Code E. Basis of energy property. If the partnership provides an attached statement for code E, use the information on the statement to complete the applicable energy credit on Form 3468, line 12. See Energy Credit in the Instructions for Form 3468.
Code Z. Section 199A information-Qualified Business Income Deduction (QBID). Generally, you may be allowed a deduction of up to 20% of your net qualified business income (QBI) plus 20% of your qualified REIT dividends, also known as section 199A dividends, and qualified PTP income from your partnership. The partnership will provide the information you need to figure your deduction.
Both pieces of information are on the statement that is referenced in Box 20. Once you have those you can complete the entry of your K-1 in TurboTax.
