Predoctoral NIH NRSA grant stipend

I'm a US citizen and receive a stipend as part of an NIH NRSA predoctoral training program.  Per IRS guidance, my stipend is not considered wages, and I do not receive either a W-2 or a 1099-MISC from my university.  Please advise on two questions: (1) do I need to report this as imputed income on my 1040?  And (2) how do I enter this into TurboTax?  I'm currently using the Deluxe edition.  Thanks!
