Retirement tax questions

Thank you for taking the time to answer my question.

 

So when I "undid" my $8000 Roth IRA contribution should have I recharacterized it to my Traditional IRA vs. transferring the money back to the original source of the funds which was my regular taxable  brokerage account?  If so, can I rectify this by contacting the account custodian (Vanguard)  to correct my error if I do so by April 15, 2025?

 

Any additional information you can provide would be greatly appreciated. Thank you.
