TurboTax is suggesting the following which is different from your suggestion but also did not specify the breakdown of 2 1099-Rs to submit.
Here is the suggestion from TT:
Steps to Take to Remove an Excess Salary Deferral
1. Figure out which retirement account you want to remove the excess salary deferral from. You can use IRS Publication 560, Retirement Plans for Small Business, to help you decide.
2. Notify the plan administrator (the company or broker that handles your retirement account) that you have an excess salary deferral as soon as possible.
Depending on the rules of your plan, and whether the plan administrator is notified sufficiently ahead of the tax return due date, you may be able to withdraw the funds to avoid paying additional taxes on the excess deferral. If you are able to withdraw the funds, here is how to report that:
1. Report the excess deferral on your 2024 return in the Income section for Retirement Plans and Social Security whether or not you received a Form 1099-R before you file your return. Enter as much information as you can. Report the excess deferral amount in boxes 1 and 2a, and use code P in box 7. Indicate that this is a 2025 Form 1099-R.
2. In 2025, you will probably receive two Forms 1099-R. One reports the excess deferral amount. The other reports the earnings on the excess deferral enter both of these forms in your 2025 return, and we'll only add the earnings to your 2025 income
