TT600 errors, including TT600, TT601, TT602, TT603, AND TT604, are typically validation errors. This means you may have entered something into your return that TurboTax cannot understand or has not been programmed to accept.
The most common example is:
- Quotation marks, ampersands and other special characters in any fields that accept text, such as your name, address, your dependant’s names, etc.
Unfortunately, the errors don’t provide much context as to where the error is. In all cases, technical support should be contacted if you encounter a TT600 error.
So, if you’re getting a TT600-series error, please call us.
