Form 8283 is required to be mailed in IF you have donations over $5000 where a signature of an appraiser and/or a signature of an official of the charity is required. In this case, Turbotax will also include a form 8453, which is a cover page for mailing documents that are required for certain e-filed returns. This form and the address will be included if you download or print "all forms and worksheets."
If your donations are less than $5000 and no appraiser signature is needed, then Turbotax will include electronic copies of for 8283 with the e-filed return and no paper copy is required to be mailed.
