Type 'k1' in the Search window, then 'Jump to k1' to enter your K-1. There is a box to check if your K-1 has more boxes than 1, 2, and 3 (screenshot).
If your final K-1 differs from your draft K-1, you could Amend your Return.
Or, you could apply for an Extension, and wait until you receive your final K-1 to file your return.
