Is there a way to find the account number of a linked account (e.g., to figure out which Schwab account is linked to my TurboTax account)?

[Critter-3]

Broker's accounts cannot be "linked" to any of the turbotax programs ... so do you mean you want to import the broker information into the return?   If so you are too late for 2019 or earlier and too early for the 2020 tax year.  Any entries now must be done manually.

Is there a way to see the account that you lent for the refund to go into or change it

@Iwasnothing2u   Did you use the Online version?   How to review the refund method

You can only change it before you file.  Go through the File tab to change it.

I’ll try thank you

What do you mean "LENT"?    If the taxpayer's name is not on the account then that bank will most likely refuse the deposit and send it back to the IRS and they will convert it to a paper check ... the conversion can take a month or more.

Here is how you can see your deposit information:

Your direct deposit information will be at the bottom of your Form 1040.
