Hello @plattom
Thank you for reaching out to the Community regarding your issue. If you would like to void the check that was sent out you'll want to contact the bank and let them know what check to void. This way you're able to keep it inside of the Quicken register like requested. You'll need the check #, date, and who it was written to generally for the bank to be able to do this.
If you have any questions please let us know.
Thanks,
Quicken Francisco
