I already filed but want to know if I could still get a loan on my return?

No.  You had to select it (if it was offered to you) before you filed.  And then you don't get until after the IRS accepts your return which won't be until they open Feb 12 .

No.  Once the return is file the tax refund advance is no longer available.
