Investors & landlords

Why is that a defect?  If TT stands behind their computations how can they then allow someone to override something and still be held to that same standard.  Makes no sense.
There is no defect, you just can't efile.  You can still prepare the tax return, you can still mail it in, so not sure the issue other than you want to OVERRIDE TT's policy.  That is not a defect.
A simple option here is to split the cost basis between the two returns and then you have TT compute the depreciation accordingly AND then you could efile.
