I took a late RMD from the IRA, so I need to file Form 5329. Per the IRS instructions, I can request a waiver on the fee under the following circumstances:
"The IRS can waive part or all of this tax if you can show that any shortfall in the amount of distributions was due to reasonable error and you are taking reasonable steps to remedy the shortfall. If you believe you qualify for this relief, attach a statement of explanation and file Form 5329."
How can I attach a document like this to my FreeTaxUSA return? There isn't an option to upload different types of documents in the attachments page.
