Transferring from an old mac 10.7.5 to a new mac was not working properly. (It was making an untransferable .pdf file) Finally discovered that if I made a DUPLICATE (file Duplicate not file Save) of the tax return and then copied it to the flash drive it saved with the proper extension and worked fine! Was told I may have to manually insert the data. Don't worry - that is NOT the case! Hope this saves someone a few hours!
