My statement numbers have changed, A LOT. LOWER

I'm 60. I download my statement every six months. I downloaded it 3 weeks ago. Two days ago, when the website was down, then back, I downloaded my statement again. My estimated payments are WAY different. DOWN. Like $150 at 62 and close to $400 at 70.

I understand they can fluctuate a little, but I've never seen BIG shifts like this. Obviously it has me upset. Is anyone else seeing the same?
