Hey there Alessandra, have you heard about the Home Tax Lady and her video on how to fill out a 1040x form? This form is necessary for filing an amendment. To complete the form, you will need the latest version of the 1040 X, the original return you want to amend, the IRS mailing address for your state, and about an hour of your time. Let's start with the form. At the top, enter the calendar year you want to amend. Remember, you can only do one year at a time. Fill in your personal information, including your name and social security number. If you filed a joint return, include your spouse's information as well. Use your current home address and provide your phone number. Next, select your filing status. Even if you are not changing it, this step is required. Choose the appropriate option. You must also answer the health care coverage question. Now, let's talk about the confusing part. In column A, enter all the original amounts from your original 1040 form. This includes your adjusted gross income. If this amount changes due to additional income, for example, make sure to update it accordingly. For instance, if your original return reported $60,000, but you received an additional $20,000, your correct adjusted gross income would be $80,000. If your itemized deductions have changed, indicate the change with parentheses to show a decrease. For example, if your deductions were originally $14,000 but then decreased by $1,000, the correct amount would be $13,000.

Make any other necessary changes, indicating the original amounts, any net changes, and the correct amounts. Now, let's focus...
