This fellowship income is not eligible compensation for making an IRA contribution unless it is reported to you in box 1 of a W-2. Since this was not W-2-reported income and you had no other eligible compensation, your IRA contribution is an excess contribution. Since this is your only contribution to this IRA account, you'll need to request a return of the contribution that you made. The custodian must distribute the original contribution adjusted for any earnings or loss while in the IRA. Since this was your only contribution, the entire account balance will be distributed.
Having the contribution returned will avoid the 6% penalty for each year that the excess contribution remains in the account.
