If you had two separate employers, you should enter 2 separate T777's when using TurboTax Premier.

Ok but what if you have 3 employers, turbotax only seems to allow me  to add employment expenses for 2 employers and I had 3

Unfortunately, only 2 spots are provided for employment expenses in this section as it is uncommon to claim expenses for more than two employers in a tax year.

However, you do have options:

• a) add all the expenses together for all employers and declare them as one entry. With this option, you'll need to send a note to CRA after filing to itemize the 3 different employers.
• b) submit only information relating to 2 employers and then file an adjustment to your filed return to include the 3rd.

• I have filed my tax return. Can I still make changes?
