In TurboTax, you do not enter the "Employment-use amount (Line 48)" manually. Instead, the software functions as a calculator; you enter your total expenses (rent, utilities, etc.) and workspace percentages, and TurboTax generates Line 48 in the background on Form T777.
Go to the Deductions & Credits tab in the left-hand menu.
Select Employment Expenses.
Answer "Yes" to the question, "Did you have expenses related to your employment income?"
You will see a list of expense types (T2200). Select "Workspace-in-the-home expenses."
Thank you for choosing TurboTax.
