Welcome to the Community space, @Dfg1. I'll share details about adjustments with Simple IRA and Secure 2.0 inside QuickBooks Online (QBO).

I recognize how crucial it is to adjust the Simple IRA to fit your specific amount and percentage requirements. After assessing our current capabilities, I can confirm that this feature is still unavailable, and we cannot provide a clear timeline for when this will be available. Since there are no options to accomplish this within the system, I recommend contacting your Tax ProAdvisor for help managing these changes outside of QuickBooks Online.

Furthermore, you can check this page to help manage contributions inside QBO: Set up or change a retirement plan.

Feel free to visit us here in the Community space if you need assistance managing employee contributions or have any questions related to QuickBooks. As always, I'll be around to extend a helping hand. Stay safe.
