The Ministere du Revenu tax agency (Quebec) is set to default to use the piggyback option. If this tax agency was used in a single transaction, you cannot change this setting.
There are two options to fix this issue:
1. Make the vendor inactive and create a new tax vendor. Using this option will make the data file ineligible to conversion to Quickbooks Online.
2. Use Data Services service to uncheck the piggyback setting:Quickbooks File Services
