I used (interactive "x") in IELM just now, but it only returns nil and didn't let me input the Lisp object. How can I use minibuffer in IELM?

Best regards.

interactive is not meant to be used interactively, it is merely a
declaration within functions and lambdas. Check C-h f interactive RET
Try read-from-minibuffer in combination with read.

Try:
(defun foo (expr)
(interactive "xType an expression: ")
(message "It seems you typed %s" expr))
and then, from ielm:
(call-interactively 'foo)
or: M-x foo RET
