Entering multiple K-1 AG codes for previous tax years

[John1946]

There are three AG entries on my LLC K-1 for 2021 through 2023. Do I enter only the previous (2023) tax year AG or all three AG entries?

Since TurboTax doesn't process your entry for Box 20 Code AG, you may enter one amount or a total of all three amounts provided for Schedule K-1. 

According to IRS Instructions for Form 1065 Schedule K-1 Code AG. Gross receipts for section 448(c), you may need this information to figure the gross receipts test under section 448(c).
