E filing to physical filing ward(changing)

I have e-filed to a senior citizen whose interest income is Rs.50k (tds detected at 20% by bank for non- availability of PAN) assessment officer assessed the income by issuing u/s 143(1) notice. The AO mentioned mis-matching of tax credit under form 26as. On the other hand, I have physical form 16a. Under intimation by AO, rectify the tax credit & apply for refund. My problem is: 1. No support from bank other than form 16a 2. e-filing rectification only available on online(no physical form submission available) 3. How can I transfer efiling ward to physical ward. with regards amirtham, income tax practictioner (new) Thanks in advance
