1099 upload problem

Good morning. In TurboTax, I'm having problems uploading tax forms from financial institutions for which I've done this routinely for several years, and for which the forms (mostly, various 1099's) are already available on their website. When I try to upload into TurboTax, and provide login info for my account with the financial institution, a box opens with red letters saying "ERROR for site owner: Invalid site key". Any advice or perspectives on this? Thanks.
