Do you mean "High Sierra" (10.13.4)? There is no known problem with Sierra (10.12).
That is a known issue that seems to have been created by Apple with a change in OSX 10.13.4. There was no problem with OSX 10.13.3.
Since this is not a defect in the TurboTax software, but is due to a change that Apple made which causes an internal Apple java script function to crash while reading an embedded java script component in the TurboTax application, TurboTax will not be issuing any update to the TurboTax software. However, TurboTax has issued a workaround to remove the java script from the TurboTax application so that the Apple software will not crash.
