You need to provide more details. Your post was tacked on to a very old thread.
Regardless, with respect to "going back three years", that is the maximum length for which you can file and receive a refund. Of course, you can file returns as far back as is necessary, but you will not receive a refund (even if one is due) pas that three-year time period.
Also, as has been mentioned, miscellaneous investment expenses are no longer deductible and, as a result, cannot be added to the basis of the property.
