What form are you trying to fill? I have the installed Standard version. Nearly all of the T2125 is fillable except for CCA which is calculated and any personal use part which is calculated. The business use of home portion is calculated but is based upon directly filled cells. It is the same with the T776. Schedule 1, however, is almost if not all, filled by other ares of the return or calculated cells. Much of this type of software is specifically geared towards those without the knowledge or ability to fill the tax return without errors.
You can fill all of the forms you require from the CRA website, but it is truly manual and does not perform the mathematical calculations you require.
