Is it normal for my federal refund to differ when trying to file in turbotax and credit karma?

[yaheny]

I'm trying to file my taxes but turbotax charges me for adding my 1098T and credit karma does not however my federal refund in turbo tax is much higher than what my federal refund for credit karma is. I was wondering if it's normal? Because if it is, then I would file with turbotax because it would only take $100 away and I would still have a bigger refund than what credit karma is telling me.

it's not normal, but you get what you pay for  😊

Thank you, would you say that it's different because I'm filing my taxes wrong? Because I put everything they asked me for but this is my first time filing my own taxes.

or it could be Credit Karma's product is flawed.....

1) the tax law is complex.

2) the q&a can be confusing.

3) the software is not really intelligent and still allows you to make errors.

For best results, you should have some idea of what you're doing, since you are self-preparing.

if it is your first time filing and you are a student  under age 24 at the end of 2019, 

it is your parents who should be entering your 1098-T on their return. And you do not, unless you got scholarship money that you did not pay to your university.
