Hi there, daa1.
I can help you record your reimbursement. However, just a disclaimer: I'm unable to recommend an account to use, but I can suggest what transaction to create to show that you've reimbursed yourself.
You can add yourself as a vendor, and create a check for yourself for the reimbursement. On the Check page, select your business account as the source of funds. Then, in the ACCOUNTS field in the table section, choose your equity account (or the account you used when you paid the sales tax). The check (reimbursement) should offset the balance of that account.
Please have an accountant check your transactions, and verify if you can use a liability or an equity account instead.
Let me know if you need more help or if your accountant has challenging instructions.
