@Mike9241 It's working now! Now just the SEP IRA contribution went to both my LLC and my trading Sole Proprietorship. I see them in the QBI Deduction Smart Worksheet of both.
By the way, I know sometimes the IRS delays the deadline to contribute to retirement plans such as when there are disasters in some counties. Is it too late in California now to contribute to 2023 solo 401K, or convert some traditional IRA to Roth IRA to be counted as part of 2023?
