Hi I have Turbotax deluxe 2018 and I can not print a federal tax return to send by mail it gives me a TI600 error.  I can print for my files  and even print the provincal report.  I also have turbotax 2016 and  2017  and they will not print the federal either any idea would be welcome since,  I have to send beofre end of month
