I accidentally filed my 2025 taxes under a different intuit account. can I bring that to my main account?

No for security reasons. You did not filed 2025(due 4/15/2026) you filed 2024. 

next year just use this account

Turbotax only supports the current year and the prior 3 years so you could not open your xxxx.tax2020 file.

in addition, TurboTax deletes all items older than 7 years just like the iRS.

so you should always save a PDF of a return to your computer, and because computers do fail,  a second PDF on some other store media. Or even print out a copy.
