Expenses on Schedule J vs. Means-Test

[redyhws]

Is it wise to put "IRS guideline" expenses (i.e., food, transportation, etc.) on Schedule J if you aren't really sure what your monthly expenses will be going forward? I am concerned that Schedule J shows more disposal income than the Means Test (but this is mainly due to the fact that Social Security income is listed on Schedule J and some of my expenses are not as high as IRS standards).
