Some of the things you list are not repairs to be deducted, they are improvements to be added as assets and depreciated.
An improvement is a property betterment, that adds value to the property or extends the useful life of the home or of its main subsystems. This is in contrast to repairs or maintenance, which only keep the property in as-was or as-is condition. Repairing a furnace igniter or a hole in the roof is a repair, but replacing the furnace or replacing the roof is an improvement, because it extends the working life of the roofing or HVAC systems in your home.
Improvements to a home office are listed as an asset to be depreciated. I believe the general recovery period is 40 years for business property, although some classes of property might have different recovery periods depending on the expected life of the improvement. You must list the improvement and let Turbotax deduct the expense over it's expected lifetime. Depreciation for improvements also affects your capital gains when you sell the property. In some cases, items costing $2500 or less that are normally depreciable can be expensed instead. I don't know all the detailed rules, but Turbotax will.
You need to divide your expenses into improvements and repairs, and list each improvement separately as an asset. Allow Turbotax to calculate the depreciation and the recovery period, and if the improvement qualifies for the expense safe harbor, you will be offered the option. List the repair and maintenance only under repairs and maintenance. If your expenses are still disallowed by your net income, you must leave them on your tax return. You must claim items when the work is actually performed, but unused expenses may carry forward.
