Hello TurboTaxBrenda,
I cannot give you an exact number of lines, since the individual requirements by TurboTax users vary widely. All I can tell you is that the fillable T1135 form that can be downloaded from CRA allows for at least 30 additional lines. And from reading posts by others I understand that other company's software allows for 15 lines and even 26 lines. These numbers are no maximums, but people simply stopped adding lines. You may also want to check your own products as I have read that the T1135 in the online version of TurboTax does allow the addition of more lines.
