Investors & landlords

@TaxGuyBill  why is it too late to "waive the carryback"?  do i need to submit whether i want to waive the 1st year there is an NOL to use?  so now my only option is to amend 2014, and 2015 return, then 2017?  

so do i need to amend the historical years return first, before i can file the 2017 return with the right numbers even i know what are the right numbers to put now?

The entire $25,000 is allowed, and you can't choose to take a smaller amount. - is this by an IRS rule that we either allowed the whole $25k or nothing?  or a turbo tax system thing?  

Thanks!
