@_Maria_ , then the treatment should be the same --- the Publication 970 referred to by @DaveF1006 is a good source for separating out taxable / reportable income from that not required to be reported. I am assuming here that the fellowship grant comes to you directly and not through the institution that you are affiliated with -- so keep all documents regarding this , just in case IRS wants to see.
Is there more I can do for you ?
stay safe
