E-filed ITR-2 instead of ITR-1

Hi Friends,

I tried e-filing for the first time this assessment year. I have income from salary and income from a house for which I am repaying home loan as well. Initially I uploaded an ITR-2 and got ITR-V. I had to pay excess tax than deducted from TDS and came to know that I could pay it online in NSDL website. I paid the same and uploaded the revised ITR-2 after a few days. I got an ITR-V for this as well. I haven't sent both the ITR-V's to CPC yet.

Now, I came to know that the correct ITR for my category is ITR-1 and not ITR-2 through my friend. What would be the best possible way to correct this mistake?

1) E-file ITR-1 with the income details under "revised" category quoting the acknowledgment number? In this case which acknowledgment number should i quote?

2) Don't send both the ITR-V's received which makes these e-filing's null and void and file a fresh ITR-1 under "original" category?

Or is there some other procedure?

Thanks in advance for your help.

Regards,
