TDS Shown Manually

Since TDS was not showing as per 26AS in the Pre-filled form, I shown the TDS manually as per 26AS. While mentioning the TDS a sum of ₹1000.00 shown excess due typing error. I am actually eligible for refund of ₹1450, but due to typing error the refund of ₹2450.00 is showing in the filed ITR. Should I submit revised ITR or the IT Department will rectify the error and actual refund will be given or not. The ITR has also been e-verified. I am eligible for refund in both the case. Instead of TDS ₹1,62,500, I wrongly mentioned ₹1,63,500 hence a difference of ₹1000.00. Please advise me soon. Please also advise how a rectified ITR in this case can be submitted. Will I be treated as a defaulter. This is only a difference in the amount of Refund and I am not to pay any further tax. Experts are requested to suggest me.
