Charitable Carryover

I itemized my taxes in 2020 and had a charitable carryover of about $12,000. Then, I took the standard deduction in subsequent years (2021, 2022, 2023) when not working (no income). I was required to file taxes those years since I had insurance through the Affordable Care Act (form 1095a received).

 

Question: I plan to work this year (2024) and had thought that the carryover is good for 5 years but after reading another post, am wondering if I am wrong -- since I took the standard deductions in previous years, there would be nothing more that I could carryover?

 

Thanks in advance!
