Need a CPA that is well versed in Solo401k Taxes and Corrections

[Saivivek Bogale]

I have both W2 main job and 1099 moonlighting income and set up a solo401k for my 1099 income. I made an overcontribution via the aftertax mega backdoor roth conversion into my solo401k. The plan is set up at my mysolo401k.com, who is only a plan sponsor, and I am the plan administrator/trustee. The accounts are held at fidelity. Mysolo401k only issues a 1099R for the year when the conversion is made. I made the overcontribution and conversion in 2025 for tax year 2024, so they will not issue that 1099R until 2025 taxes come around.

I am based in Texas and filed a tax extension for this current year, but need a CPA who is well versed on the corrective steps needed to be taken and filed for this overcontribution.

I am open to CPAs located elsewhere as well since Texas does not have any specific state income tax issues. Any help would be highly appreciated!
