If the total of non-cash items is more than $500, turbotax will prepare for you a form 8283 which lists the date, place donated, and value of each item. You can still use a generic description ("used household items", for example) but you must separate your donations by date. You must also have your own detailed itemized lists in sufficient detail that you can prove the values if audited. Turbotax will not provide that proof for you.
Also be aware that you can't claim more than $5000 as the value for any single item or "group of similar items" unless you have a signed appraisal by a qualified appraiser, and you also have a signature from a financially responsible official of the donee organization confirming the donation. There is no black letter definition of "group of similar items" but if you have more than $5000 of used household items, and you try and break it up into smaller groups ("used kitchen items", used bathroom items" and so on) you might have a hard time sustaining the deduction if you are selected for audit.
