As far as I know, I can contribute to the previous year's SEP IRA until April 15th this year. So, technically, in March of this year, I am going to contribute X amount for 2023 and Y amount for 2024. Unfortunately, my investment app doesn't have an option to select the year for the contribution. My question is, for tax purposes, what do I need to do on TurboTax to inform the IRS that I want the X amount to be allocated for 2023 and the Y amount for 2024?
