if this is an S-Corp and he was paid wages during the year but failed to get a w-2, first you need to use the iRS website to see if a w-2 was filed https://www.irs.gov/individuals/get-transcript . You want to see if there is a wage transcript. an LLC operating as an S_corp can pay wages to its members. An LLC operating as a partnership may not.
********
let's say it's an S-Corp and HB got paid wages but no transcript. then contact the IRS at
800-829-1040 for assistance. You must provide name, address (including ZIP code), phone number, social security number, and dates of employment. You must also provide your employer’s or payer’s name, address (including ZIP code), and phone number. The IRS will contact your employer or payer and request the missing form. The IRS will also send you a Form 4852. If you don’t receive the missing form in
sufficient time to file your income tax return timely, you may use the Form 4852 that the IRS sent you to file with your return. With form 4852 you reconstruct the wages HB got paid as best you can. Turbotax has this in at least some versions
***********************************
if the LLC extended its return it has until 9/15/2023 to issue the k-1. if one isn't received within a week thereafter there is no easy resolution. I would suggest you report nothing for the K-1 and as a safeguard file form 8082 with your return. For this you should seek professional advice. Besides the question of HB having K-1 Income/loss there is a question of how to handle whatever tax basis he has in the LLC. for an S-corp HB may also need to file form 7203 and include any required K-3 reporting which is not possible without the k-1/k-3.
