You probably don't need to worry. If your income estimate was accepted by your ACA Marketplace and you received subsidies, in most cases you'll complete Form 8962 as normal. See the instructions for Form 8962, especially the part where it talks about income under 100% of FPL.
Depending on your state and what information you've agreed to provide them, if your income for 2023 is too low, your Marketplace may try to cut off your 2024 subsidies. If you're concerned about 2024, I'd call your Marketplace and ask them.
