This is my first time filing taxes at the age of 25, what all do I include and how far back do I go?

[NCperson]

you are including ONLY 2019 income - did you receive tax forms in the mail?

I mean I don't know how far back I can put information in for. So thats why I'm asking. I have received some things in the mail but not much

[NCperson]

understood and you can only go as far back as 2019.  all the tax documents you received must state '2019' on them. if they state '2018, 2017, etc.  you can not use them for your 2019 tax returns. 

what kind of information are you otherwise concerned with? be specific.

As NCperson said, a 2019 tax return can ONLY have information for 2019 on it---no other tax year.  If you had income for any earlier years, and you need to file a tax return for an earlier year, we can help you with how to do that.  BUT do NOT try to put any income from any year other than 2019 into the online software program.

When you complete a 2019 tax return it must have ALL of your 2019 income entered--so if you received W-2's from more than one employer, they ALL have to go on the same tax form.  Or if you received any sort of 1099's etc. they must also be included.    Do you have any other 2019 tax documents--like a 1098T or 1098E?  (For tuition or student loan interest you paid?)
