Hello, linajanehayden, trish26.  

Voiding an invoice will always affect your AR account and Balance Sheet. As a workaround, you can void it then create a journal entry to offset the amount.
The journal entry should have the same date with the voided invoice and should use the same accounts as the invoice did. Once done, create another journal entry with the current date using the same accounts to offset the first journal entry created. 

It’d be best to consult your accountant before doing these steps for proper recording.
