I import 1099B from Merrill Edge. Turbotax summary different with Merrill Edge summary around $30. Look like the Turbotax round up number at some data. What should I do?

1) I import 1099B from Merrill Edge. Turbotax summary different with Merrill Edge summary around $30 (gain, loss, total sale...). Look like the Turbotax round up number at some data. What should I do?
2) Last years, all 1099B data are attached to 1040 form. This year only 1 page of data is attached. Is this normal?
Thank you.
