First go to the assets section of the TurboTax 'Home & Business' product to see if you qualify to take the election. If you qualify, then go to the expenses section and enter the item there. Essentially, qualifying for the 'De Minimis Safe Harbor Election' means your item can be entered as an expense and not an asset. This usually means that you get a greater tax benefit.
Additional note: Please enter those elections in the 'other miscellaneous expenses' category under the 'other common business expenses' section.
