Should I claim my expenses this year or next?

What expenses?  We cannot see your screen or your tax return.  Provide some information.

Expenses for what? You need to provide some context here.

@stellaa0223 You need to provide more information and more detail.   Just saying you want to include "office expenses" does not give us enough to go on.  We do not know if you are a W-2 employee or if you are self-employed.    We know nothing about your tax situation except for what you tell us here  --- asking us to guess will not work out.
