Investors & landlords

When using the  "Step-by-Step" method to input data from my records to create a 2017 return in TTX some of the calculations on the 2017 return in TTX match my original paper copy and some don't.  I assume the discrepancies may be due to the "critical update" issue or I re-entered something wrong.  I thought about a workaround so the data & calculations match:  Can I enter the data directly onto the "Forms" view in TTX?  Or can I correct what doesn't match using the "Forms" view?
