one or more of my tax forms is currently unavailable, preventing me from proceeding reviewed the FAQ on locked forms and none of the listed forms apply to my situation?

I am consistently receiving an error message stating that one or more of my tax forms is currently unavailable, preventing me from proceeding with my submission. I have already reviewed the FAQ on locked forms, and none of the listed forms apply to my situation. Here is what I have tried so far: • Contacted support and spoke with three agents (without resolution) • Cleared cache, cookies, and browser history • Restarted my computer • Attempted filing on both Google Chrome and Microsoft Edge • Tried the TurboTax app on my iPhone • Redid my entire return from scratch • Waited 24 hours and tried again
