turbotax t777s showing incorrect deduction with detailed method

[logicallayer]

Hi,

Although based on the CRA calculator I see deduction of $4,000+ but when I look at turbotax deduction after filling all info accurately it shows only a difference of $50 in deduction and refund in comparison with the simple method.

Is there an issue with turbotax t777s detailed method form or am I doing something wrong?

I found the issue.

I had to go to the t4 and select yes for working from home due to covid19. This was hidden until turbotax dedicated an error before filing.
