Do I need to fill out Form8283? I am deducting a large QTY of the same item that equates to $4090 in value [It'sDeductible]. Turbotax isn't telling me to fill it out.

You must include form 8283 if your non-cash donations are more than $500.  Turbotax will include this form automatically.

For non-cash donations over $5000, you may be required to obtain the signature of a financially responsible official from the charity, and the signature of a licensed appraiser, on a paper copy of form 8283, that you mail to the IRS after e-filing the rest of your return.  Because your donations are less than $5000, turbotax will not tell you to print the form and collect signatures, but the required form will be created electronically automatically.
