Hi there, Angela902. I can share some information about voiding checks from a closed fiscal year in QuickBooks Desktop (QBDT). 

Voiding checks from previous closed fiscal years and reissuing them in the current fiscal year without changing the financial statements of the closed fiscal years can be a complex process in QuickBooks Desktop (QB Desktop). 

For the uncashed check, you can record it as a bank deposit. Let's make sure to use the same account for the expense accounts and the current date.

Here's how to create bank deposit:

1. Go to Banking menu and select Make Deposits.
2. Hit OK on the Payments to Deposit window.
3. Choose the account where you want the money deposited to.
4. Enter Date.
5. On the Received From column, select the vendor.
6. Fill in the Chk No and Amount fields.
7. Hit Save & Close.

Then, create a write check again.

Check out the following articles for more information: 

• Record Deposits/make Deposits.
• Create, modify, and print checks.

Let me know how everything turns out, or if you have any issues after following those steps. I’m always here ready to help. Have a good one!
