Shareholder - have you elected to be taxed as an s-corp or form a c-corporation?
You should have create a bank type account for checking as well as cash on hand
there are several ways to do this, I prefer
1. the amount you spent before establishing the real bank account, deposit that amount to the cash type bank account and use the loan account as the source (from) account for the deposit. Then use write checks, do not print, on the cash account to record the expenses you already paid. (write checks is a data entry form)
2. the balance of the loan is deposited in the bank checking account, and use the loan account as the source (from) account for the deposit.
Delete all the entries you made in opening balance equity. that account does not apply in this situation
