Turbotax says free. I see all over online the lawsuits in the states. I am in canada, on disability and my taxes are so simple a monkey could do them. Just need free

Keeps trying to update me to deluxe, $39.99 which is crazy.  How do I just file, free as advertised?  The only thing I have is medical expenses but it was 100% FREE when I did it on here before to enter them as its so simple.
