Investors & landlords

I certainly hope for a quick solution,  since I did pay for the conversion from CSV to TXF via investotek.com.  This was a nightmare to deal with and finally managed to convert, now it is residing somewhere in Excel as a TXF and have no clue where or how?  If I can find it than it should be easy to import, but I know that I will have to tweak the 80 or so transaction with additional information.  The only saving grace is having the 1099B from Fidelity to double check the work and the download if I ever get there.
