How to enable Refile Option in 2018 ProTax? Apparently I followed all steps (Duplicate Return, T1 Refile form) but to no avail. Refile option is still greyed out.

Hello usersehrish,

I love that you're using the ReFILE option that's available to QuickBooks Online Accountant users through Pro Tax. Mistakes happen and we know that which is why we give you the option to refile or amend a return after it's been transmitted. It sounds like you've done a great job following the steps, but it appears that there's an issue preventing you from completing the process. Let me give you a hand.

If you haven't already referred to our article on the ReFILE feature, check it out here for the full step-by-step instructions on how to ReFILE a return: ReFILE or amend a T1 or T2 return in Pro Tax.

If you're sure you've followed all of the steps correctly, it's worthwhile to run through the browser and internet troubleshooting steps below. That'll help to determine whether the issue lies within QuickBooks and Pro Tax, or whether it's an issue with the images and files stored in your internet browser. 

• Clear your browser cache if you're using a browser
• Clear the app cache if you're using the QuickBooks Online app for Windows or Mac
• Try a browser if you're using the app
• Try a private browser window
• Try another browser type
• Make sure you're using a supported browser and system
• Reset your Internet or try on another computer or device

If the above options still don't allow you to proceed with the ReFILE, reaching out to our team of support experts is the next best option.
