Retirement tax questions

I called the custodian and they said that they will not file the 990-T and that my SDIRA LLC within the custodian account will have to and pay any taxes due to UBTI.

 

This is preferred so I control the process and not share my SDIRA LLC return with the custodian, less fees as well.

 

Any concerns with the above?

 

Does the IRA LLC need to file a 1040 and within it the 990T?

Can TTax help with the LLC tax return and relative 990T?

 

thanks
