I've received some money from different accounts that my mom had. One account was an IRA and I put that into a conduit IRA already. She had a mutual fund that I had to cash out and I've received my 1099 for that. I also had to cash out a cash management account and checking account but I've not received a 1099 for that. Do I claim that as income on my taxes?

Check with tax professional, these should be inheirtance not earned income and not taxable unless they exceed the exemption limit.

Agreed. The money received from an inheritance is NOT subject to income taxes EXCEPT for any traditional IRA that is cashed out.
