No, Form 8275 is not appropriate for this situation. I would suggest preparing your return without the K-3 to determine if you will owe additional taxes on your tax return then pay those taxes by April 18, 2023, and file Form 4868 to apply for an extension of time to file. Once you receive your K-3, complete your return and file it. If you owe any additional tax at that time, the penalty for late paying should be small.
