How i get my tax

It's not clear what you did and what you are asking. You would probably not be required to file a tax return with only one month of income but if you had federal tax withheld, you should file to get a refund. You must create an account and log in to the Free Edition and complete a tax return form 1040. You enter your W-2 on that form using the program. When you have completed your return, you efile your tax return by following all 3 steps in the Filing section until you click on the big orange Transmit Returns Now button. If you did not file a tax return for tax year 2018, then you enter the number 0 for the AGI to be able to efile your tax return. 

When you are completing the return if you are getting a refund, you can enter your bank account information on your tax return to get a direct deposit of your refund or you can choose to get a check in the mail. 

If you did all of this and efiled your return and it was accepted by the IRS, then you can track the status of your refund using this link:
