I'd be delighted to help you create and file your 1099s with QuickBooks Online. Let me guide you through the details of the process.
If you pay contractors using cash, checks, or direct deposit, you'll need to file 1099s with the IRS. QuickBooks Online can assist you in seamlessly preparing your 1099s using the information already in your account.
If there are accounts that are not listed in the Add/Edit accounts and sub-accounts and Less Common section, I recommend reviewing the accounts in your Chart of Accounts. It's possible that the account types of these entries are different and should be as COGS, Expenses, Assets, or Liabilities. Another reason also is to make sure that the vendor has to opt for tracking payments for 1099.
