Just when I had a side issue about Form 3115, someone took that GMC DeLorean and cranked it to 88 mph to bring this thread back to the present.  Hello, Lisa. 

I didn't even looked at the original post date(s) and gave @TaxGuyBill  kudos when I read his comment:

Using an incorrect Basis is not a changing in accounting method (it is a "mathematical or posting error"), so Form 3115 can't be used (some people say it can be used in the year of the sale, but I'm still not convinced of that).

I totally agree with the comment.  Thus the kudos.

My burning question is, does statute of limitations work here, thus invalidating my kudos?

RE: I did not "change the depreciation schedule" but I read that the IRS treats it as a change if you made a depreciation error two years in a row.

The only comment I could make about the statement : I don't doubt you read that. 

Have a fantastic Sunday!!
