We closed one checking acct in March and opened another on April 1. ( I wasn't here then, the company converted from Vista to QB's)... I don't know why but they left $50k in the old checking acct (only in qb's)... they took about $25K of the March transactions and changed them to the new bank I think because that's where they were going to clear but now the old acct should be zero but I'm not sure how or where to make an adjustment. The new acct has a negative $25k for March and the old has a positive $50k... What is the best way to close the old acct and bring to zero as of April 5.. No one from Intuit is touching this question..

Do a transfer of $50000 from one account to the other, then edit the account and make it inoperable

Yes, thank you for your answer!
