It is an expense. I typically would post these to either a Software Expense, Office Expense, or similar type expense account.
QBO will offer suggestions for posting transactions, but should be reviewed for accuracy because it can be wrong often - especially in a new file as there is very little historical data for QBO to use when making suggestions. QBO will also suggest a rule if you code a transaction the same way 2 or three times in bank feeds, so if a rule was setup with incorrect coding you will need to go into the Rules tab to adjust the rule to reflect the correct GL account.
