Can I file two tax returns for two years, one for 2018 and one for 2017?

[LC4]

I am an international student, back in 2017 I did not know that I need to file fax returns. But now I know, so, after I filed this year's tax return, I was told that although I did not file my last year's tax I can still do it. So, my question is can I file two tax returns for two years, one for 2018 and one for 2017 since I already filed one for 2018? Or do I file an amendment, or I can only wait till next year?

Yes, you can still file your 2017 return this year even though you filed 2018.  But, you won't be able to e-file it or use TurboTax online - you will have to print and mail your return.  

Follow the instructions in the article below (you will have to purchase the 2017 software) -
