I work in a real estate office as a broker how do I claim my expenses

[TomD8]

If you are paid as an employee (you receive a W-2), under the new tax law your unreimbursed employee business expenses are no longer deductible.

If you're paid as an independent contractor (you receive a 1099-MISC), you deduct your allowable business expenses on Schedule C.

I have expenses but no income from 2018

Are you using the Desktop program?  You can fill out schedule C without income.

For Home & Business version:
Go to Business tab- then Continue
Business Income and Expenses - Click the Start or Update button

Then click EDIT by the business name and the next screen should be a list of  topics,
Business Profile, Income, Inventory/Cost of Goods Sold, Expenses, Assets, and Final Details last.

Under Business Expenses, Click Start or Update by Other common business expenses.  You should see the list of expenses and amounts you entered.
Then click the start or update button by the expense you want to add or edit.

You might need to fill out some basic info on your business first.
