For AY 2019-20 I got demand notification because in TDS schedule I entered MUMI04992B (happens to be valid) instead of MUMI04922B as in 26AS inadvertently. It is my data entry typo error. Tax credit claimed under this entry is demand amount. CPC is correct based on my data entry mistake.
I am so confused on filing rectification and creating return data correction XML file. What should I do ?
Any help will be highly appreciated.
Thanks in advance.
