Deductions & credits

Thank you.

I looked at Pub 547.  Is it necessary that I follow the guidance on page 15 on how to postpone a gain?   It says I have gain in the year I receive the insurance proceeds.  Per the instructions, am I required to attach a statement giving details, etc.?  Since I did not replace the property in 2023 do I also attach another statement saying that I am choosing to replace the property within the required period.  I'm not sure at this time that I will, in fact, have a gain.  If I am required to attach these statements is there a way to do this in TT so I can file electronically?  Is there instead, an election to defer the gain on involuntary conversion?  Or do I file without the statements and then amend the 2023 return if I have a gain?  I find this very confusing.
