Taxes on estate

I have a TIAA retirement Fund and a Schwab IRA.  Two Questions:

 

1.  I have a charitable fund as a 50% beneficiary of both.  I presume there will be no tax on these distributions?

 

2.  If I leave the other 50% of both accounts to a Trust (for distribution) will the Trust be taxed upon receiving the money?  Alternatively, if I leave this 50% to an individual (daughter), would she be able to take the money over 10 years to spread the tax liability?

 

Thank you,
