Wrong coad selaected

If the section is correct and only error is that you deposited one company deductee TDS along with non company deductee TDS, it will not result in any problem while filing the e-TDS returns. You can go ahead and file the TDS return.

But if you insist on Rectitification of errors in challan, then you may contact your bank within the following time limits:

Sl. No.	Type of Correction on Challan	Period for correction request (in days)
1	PAN/TAN	Within 7 days from challan deposit date
2	Assessment Year	Within 7 days from challan deposit date
3	Total Amount	Within 7 days from challan deposit date
4	Major Head	Within 3 months from challan deposit date
5	Minor Head	Within 3 months from challan deposit date
6	Nature of Payment	Within 3 months from challan deposit date

However you may note that the 'Deductee' field is not mentioned above. Hence a mistake made in choosing the type of deductee is not going to cause any problems.
