In fact it says:
> The TCJA added a special rule under Sec. 174(c)(3) for the treatment for software development costs, stating that “any amount paid or incurred in connection with the development of any software shall be treated as a research or experimental expenditure.” Prior to this addition, taxpayers relied on Rev. Proc. 2000-50, which stated that the costs of developing computer software so closely resemble Sec. 174 R&E expenditures that a similar accounting treatment should be used. When this revenue procedure was issued, R&E expenditures were currently deducted. Under the TCJA, software development costs are treated as R&E expenses but are now subject to five- or 15-year amortization.
...which is what I am saying in my example -- software dev costs are now forced to be 5-year amortized.
