With the changes due to the Tax Cuts and Jobs Act (TCJA) effective 2018 I no longer itemize deductions. I think I want to switch from allocating Mortgage Interest and Property Taxes from the Tax Court method to the IRS method to increase the amount allocated to Schedule E. This will result in a bigger loss on my schedule E that I may be able to use in the future when I sell the property or have profits.
Question: If I want to change this allocation for my filed 2018 do I need to amend my return? It will not change the amount of tax refund as I am unable to deduct the schedule E loss.
Thank you
