Onebranch deducted tds on other branch which has same pan no

Hi  All,

Our company has branches in Pune and Nagpur, head office is at Mumbai

For all three locations we have Different TAN, bt wit same PAN.

But here the problem is  Pune branch deducted the TDS on Nagpur branch and paid the TDS amount to the Bank. While filing the TDS return it was found that there was mistake.

So request you all to post is there any solution for this situation, with regards to filing and challan payment what are the implications.
