OK, this was a return of contribution from your traditional IRA. Since box 2a shows $0, there is no need to amend your 2017 tax return as long as there was no deduction for this contribution on 2017 Form 1040 line 32 or 2017 Form 1040A line 17 and no nondeductible contribution reported on 2017 Form 8606 line 1 of your originally filed tax return.
