Yes but you will not be able to claim the entire amount of your mortgage payments, just the portion that represents mortgage interest, (and insurance and property taxes (if these taxes are pay through your escrow account)).
To enter your mortgage interest related to your home office if self-employed, you will need to select "I'll enter actual expenses with the Office Expense Expert" (See Screenshot #1). Then you will be able to enter your mortgage interest on the next screen (See Screenshot #2).
According to the IRS, certain expenses are deductible whether or not you use your home for business. If the expense is indirect, use the business percentage of these expenses to figure how much to include in your total business-use-of-the-home deduction. These expenses include the following;
- Real estate taxes.
- Qualified mortgage insurance premiums
- Home mortgage interest.
- Casualty losses.

If you are an employee, you will enter your home office information as a job-related expense.
