I amended my taxes to add a W2 online before I received my refund, how do I know if it went through or if I need to send in me amend?
If you e-filed it, it didn't go through as an amended return cannot be e-filed. It must be printed and mailed in.
See this TurboTax site on how to amend: https://ttlc.intuit.com/questions/1894381
