I have Turbotax Premier but it won't let me complete the Flat rate method on Form T777S. Form T2200, which not required by CRA and I answered "yes" to the question about Employment Expenses on the easy interview process. I enter the 200 days on Form T777s but the calculation box remains at 0.00. If I override it and enter the $400 on Form T777S, will I still be able to file?
