sir,
I have 2 proprietorship concern ( X & Y). In my X Tds challan I have quoted Y's TAN no. which is wrong .And I have already filed Y Tds (E- Filing) with correct TAN no. of Y. What should be done to correct the following?

I suspect you are asking questions about a tax system that is NOT in the United States, though I am NOT sure of this.

Regardless, this forum addresses ONLY U.S. tax systems.
