do I claim pay from helping my mom clean houses at age 19

Yes.  If you are being paid to help clean houses and you are 19 then you would report this as income on your tax return.  If you are part of the business or just help when you can, and are not treated as an employee, this would be considered self employment income.

To enter your self-employment income select the following:

1. Federal
2. Income and Expenses
3. Show More next to Self-Employment
4. Start next to Self-Employment
5. Yes, to you have any self-employment income or expenses
6. Enter the type of self-employment work you do and you can select that you use your name for your business
7. Click through a few more screens and you will get to a screen that says "Your XX info"
8. Click Looks good
9. Then you will come to a screen that says Let's enter the income for your business.  It will give you the option of 1099-NEC or Other self-employed income including the 1099K , cash and checks.  Here is where you will enter the money you receive.
10. If you do not select one, it will not let you enter your income
11. Enter your self-employment income on the next screen
12. Continue and on the next screen click add expenses

In the expense section, you will enter any cleaning supplies YOU purchase or the portion of your cell phone that is used for business and mileage to get to your clients houses, plus any other expenses incurred to do your job.  

This income will be reported on Schedule C which is part of your overall tax return. This also means you will be subject to SE Tax.  If you did not pay SE Taxes in 2024, and if you plan to do this again in 2025, it may be a good idea to make  quarterly estimated payments to cover your SE taxes of 15.3% and avoid penalties.
